Commemorative poster stamps are artifacts from another time. These miniature bits of advertising were popular in Europe at the turn of the century. Their appeal, utility, and popularity quickly grew, becoming ubiquitous in the United States in the 1920s.
Used on letterhead and envelopes to promote brands, products, and events, these small, ephemeral items provide visually stunning examples of the popular art movements of the time. The iconic work of famed designers such as Lucien Bernhard and Alphonse Mucha can be found on poster stamps.
